The ON Semiconductor FSDH321L is an integrated offline switch IC designed for high-performance Switch Mode Power Supplies (SMPS). It combines a Pulse Width Modulator (PWM) with a Sense FET, minimizing external components for cost-effective flyback converter designs.
Key electrical specifications include an operating voltage range of 8V to 20V and a nominal switching frequency of 100kHz, with a duty cycle of 67%. It can deliver up to 17W of power. The device incorporates several protection features such as current limiting, over load, over temperature, and over voltage protection, along with an internal thermal shutdown function and auto-restart mode.
This IC is suitable for applications like SMPS for set-top boxes and low-cost DVD players, as well as auxiliary power for PCs and chargers. It is available in a surface mount package, specifically the 8-LSOP (8-SMD, Gull Wing) configuration.
The FSDH321L also features advanced functions like frequency modulation for reduced EMI, an internal start-up circuit, and a built-in soft start.
